It's Wednesday night and there's nothing to do? We like to spend the midweek drinking a glass of wine or sipping a cup of coffee at Agora. It's a dusky place with dark heavy furniture mixed with a few Greek artifacts here and there and hip magazines you won't find anyplace else. And where else can you get banana bread or baklava while you play a game of backgammon? And as the night wears on, out come the belly dancers. They shimmy and shake their stomachs wearing sequined I Dream of Jeannie costumes as smiling patrons stuff dollar bills into their belts. You can't see that at Starbucks.
